The FormConnect apps allow you to share data with other 3rd party apps that you have installed on your iPad or iPhone. When you export the data contained within one of your forms in a file format (pdf, csv, xml, etc.) that is readable by these 3rd party apps, it will open in their app. For example, if you have a PDF reader app installed on your iPad or iPhone, you can view it on your device before you email it to someone else. If you have the Numbers or Excel app installed and you exported your data into the csv format, you can view it in a spreadsheet layout.
